我需要删除android studio中特定号码的最近SMS对话或SMS对话

Question

对话框创建：

stratified

此功能可删除完整的对话，但不起作用。

private AlertDialog AskOption()
{
    AlertDialog myQuittingDialogBox =new AlertDialog.Builder(this)
            .setTitle("Security Alert")
            .setMessage("Do you want to delete conversation?")
            .setIcon(R.drawable.d)
            .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {

                    SharedPreferences xsx = getApplicationContext().getSharedPreferences("ll", Context.MODE_PRIVATE);

                    nmr = xsx.getString("nmr", "");

                    removeMessage();
                   // removeMessage(getApplicationContext(),nmr);

                    delete_thread(nmr);
                }
            })
            .setNegativeButton("No", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            })
            .create();
    return myQuittingDialogBox;

}

这是另一个删除特定号码的短信会话的功能，但它也无法正常工作...我也被授予权限，我不知道自己在哪里弄错。

private void removeMessage() {
    Uri uriSMSURI = Uri.parse("content://sms");
    Cursor cur = getApplicationContext().getContentResolver().query(uriSMSURI, null, null, null,null);
    String phoneNo, msg;
    if (cur.moveToFirst()) {
        String pid = cur.getString(1);
        // do some process
        Toast.makeText(getApplicationContext(), pid, Toast.LENGTH_LONG).show();
        Cursor cur2 = getApplicationContext().getContentResolver().query(Uri.parse("content://sms/conversations/" + pid), null, null, null, null);
        if (cur2.moveToFirst()) {
            ////Tried with this with no luck, its Delete the whole Conversation :
            String pid2 = cur2.getString(1);
            String uri = "content://sms/conversations/" + pid2;
            getApplicationContext().getContentResolver().delete(Uri.parse(uri), null, null);
        }
    }

}

我尝试了这里提供的几乎所有解决方案，但没有一个起作用。
